MLG Protip: instead of microwaving cold pizza, put it in a frying pan and cover it with tin foil (just make sure the foil isn't touching the pizza). It will LIT'RALLY taste like it was just delivered.
"Dry here to open?" So it's some kind of moisture-activated locking mechanism, where dehydration makes said mechanism weigh less and rise, thereby releasing the lock and opening the door?
Unless... oh wait, I see what it says now. Never mind, carry on.
